Heterocyclic Terpenes: Linear Furano‐ and Pyrroloterpenoids

Abstract

The emphasis of this review is on linear furano-and pyrroloterpenoids, together with their relevant biological activities, source organisms and country of origin. First total syntheses that lead to the revision of structures or stereochemistries have been included, and 206 references are cited.

Essential Oils of Dennettia Tripetala Bak. f. Stem Bark and Leaf – Constituents and Biological Activities

“…In comparison with the previous oil, the almost total absence of sesquiterpenes should also be underlined. The latter, in fact, were represented at levels below 1%, by α-farnesene and dendrolasin, a well known furano-sesquiterpene [17]. The essential oils from D. tripetala examined here are, thus, strongly characterized by 2-phenylnitroethane, and this is in agreement with the report of Osisiogu and Agbakwuru for fruit oil [2].…”

Heat-resistant and photoluminescent indole-based poly(ether sulfone)s

“…Blue light can be converted to green light or red light using the proper dyes, which means a blue PLED is capable of generating all colors alone, while green light or red light cannot emit blue light by this method. It is well known that the indole derivatives are highly fluorescent molecules, 17 the successful incorporation of indole moieties in polymers is further confirmed by photoluminescent spectroscopy in this article. As displayed in Figure 4(a) and (b), these PINESs polymers showed increased absorption and emission intensities with the increasing content of indole groups.…”
